Brazil on Sunday recorded 1,803 new COVID-19 deaths, as a large study found that a Chinese vaccine that has become the linchpin in the country’s vaccination campaign is 50.7% effective against the infectious new homegrown variant known as P1, Trend reports citing Reuters.
Brazil, which has in recent weeks become the global epicenter of the coronavirus pandemic, saw over 37,000 new cases, the Health Ministry said on Sunday. With over 353,000 deaths, Latin America’s biggest country has the second highest coronavirus death toll in the world, after the United States.
The outbreak has recently reached its most severe phase due to a lack of federal restrictions, a patchy vaccine rollout and the P1 variant.
Sao Paulo’s Butantan biomedical institute, which tested and is now producing the CoronaVac vaccine developed by China’s Sinovac Biotech Ltd, said on Sunday a study it conducted found the shot had an efficacy rate of 50.7% against the P1 variant, and a less widespread strain known as P2.
